Abstract
1391961 Bonding of brake linings to shoe tables L FRIEDMAN 28 April 1972 [30 April 1971] 19762/72 Heading F2E Pressure is applied between brake linings 24, 26 and associated curved shoe tables 20 prior to mutual bonding by apparatus having a pair of support anvils 28 contacting the tables' internal surfaces and a pressure cage assembly comprising a pair of rigid plate assemblies having curved surfaces overlying the linings and a rigid assembly applying radially inward pressure on the plate assemblies, the pressure of the cage assembly being maintained for bonding. Two opposed tables 20 are mounted on corresponding anvils 28 of three spaced chordal plates joined by transverse ribs 34. The plate assemblies comprising two pairs of pressure plates 64, one on each end of two pairs of crossed bars 54, 56, the plates corresponding to the surface means of the linings 24, 26. The bars 54, 56 are swung apart from the Fig. 2, position to overlie the linings 24, 26 and the tables 20 by a hydraulic ram underneath, working a scissors linkage beneath the bars. In the shoe overlying position, the bars 54, 56 are held by hook shaped fasteners 68. The anvils 28 are connected via springs 46 and a rectangular spigot and socket 48, 40. Bifurcated brackets 40, 42 mounting the anvils 28 have facing shoulders which are forced apart to apply compression to the brake shoes by the apparatus in Fig. 7 which approaches the anvil on rollers in rails. When the apparatus is stopped between the anvils 28, wedges 250 are moved forwardly by hydraulic rams 214 to force apart pairs of blocks 230, pivoted at 232 on bars 220, 222, 224, 226, pivoted to a fixed part of the apparatus at their other ends 218. The outer surfaces of the blocks 230 force apart the anvils 28 until the required force is attained. A further wedge is manually driven into a hole in the socket 50 to abut the outer end of the spigot, so that the anvils 28 are retained in the stressed position. The wedges 250 are then retracted and the Fig. 7 apparatus moved back, so that the assembly comprising the pressure plates 64, the brake shoes and the anvils 28, is then placed in a heating chamber. After heating, the Fig. 7 apparatus moves forward, the wedges 250 are actuated to take up the stresses, and the further wedge is removed. The pressure is then released by the Fig. 7, apparatus, the anvils 28 are retracted by an hydraulic ram acting through a linkage, and the bars 54, 56 are brought together to permit removal of the brake shoes. The pivot centre of the bars 54, 56 may be offset from the effective centre of the brake shoes to accommodate linings which vary in thickness along their peripheries.
